Relationship between Shear stress and tensile Stress Ultimate Tensile Strength = Su, Ultimate Shear Strength = Ssu, Tensile Yield Strength = Syp, Shear yield point = Ssyp Note: The relationships below are very approximate for use only as an rule of thumb estimate if no other source of information is available... Material
Tensile-Relation
Yield-Relation
Wrought Steel & alloy steel
Ssu = Approx 0,75 x S u
Ssyp = Approx 0,58 x Syp
Ductile Iron
Ssu = Approx 0,90 x S u
Ssyp = Approx 0,75 x Syp
Malleable iron -Pearlitic
Ssu = Approx 1,0 x S u
-
Wrought iron
Ssu = Approx 0,83 x S u
-
Cast Iron
Ssu = Approx 1,3 x S u
-
Copper/ & alloys (See Note below)
Ssu = Approx 0,65 x S u
-
Aluminium/ & alloys
Ssu = Approx 0,65 xSu
Ssyp = Approx 0,55 x Syp

Note: The original data is based generally on the reference above and I have completed a very crude review to confirm the information. The copper information is however very suspect.. For copper the reference above gives a value of Ssu = Approx 0,9 x Su...On reviewing a number of copper alloys there is a wide spread from about 0,5 to 0,9 the 0.9 applied to one leaded brass cast alloy. I am tempted to remove copper from the table but as a very crude average I have simply changed the value to 0,65 please use with care or better still do not use...
